#
# Basic build targets:
#   all		all main tools and the shared library
#   static      build static binaries, requires static version of the libraries
#   test        run the full testsuite
#   install     install binaries, shared libraries and header files to default
#               location (/usr/local)
#   install-static
#               install the static binaries, static libraries and header files
#               to default locationh (/usr/local)
#   clean       clean built binaries (not the documentation)
#   clean-all   clean as above, clean docs and generated files
#   clean-dep   clean header dependency files (*.o.d)
#
# All-in-one binary (busybox style):
#   btrfs.box         single binary with functionality of mkfs.btrfs, btrfs-image,
#                     btrfs-convert and btrfstune, selected by the file name
#   btrfs.box.static  dtto, static version
#
# Tuning by variables (environment or make arguments):
#   V=1            verbose, print command lines (default: quiet)
#   C=1            run checker before compilation (default checker: sparse)
#   D=1            debugging build, turn off optimizations
#   D=dflags       dtto, turn on additional debugging features:
#                  verbose - print file:line along with error/warning messages
#                  trace   - print trace before the error/warning messages
#                  abort   - call abort() on first error (dumps core)
#                  all     - shortcut for all of the above
#                  asan    - enable address sanitizer compiler feature
#                  tsan    - enable thread sanitizer compiler feature
#                  ubsan   - undefined behaviour sanitizer compiler feature
#                  bcheck  - extended build checks
#                  gcov    - enable GCOV support during build
#   W=123          build with warnings (default: off)
#   DEBUG_CFLAGS   additional compiler flags for debugging build
#   EXTRA_CFLAGS   additional compiler flags
#   EXTRA_LDFLAGS  additional linker flags
#   EXTRA_PYTHON_CFLAGS   additional compiler flags to pass when building Python
#                         library
#   EXTRA_PYTHON_LDFLAGS  additional linker flags to pass when building Python
#                         library
#
# Testing-specific options (see also tests/README.md):
#   TEST=GLOB      run test(s) from directories matching GLOB
#   TEST_LOG=tty   print name of a command run via the execution helpers
#   TEST_LOG=dump  dump testing log file when a test fails
#
# Static checkers:
#   CHECKER        static checker binary to be called (default: sparse)
#   CHECKER_FLAGS  flags to pass to CHECKER, can override CFLAGS
#
# Other:
#   DEP=1          verbose generation of dependency files (.o.d)

# Export all variables to sub-makes by default
